SIGNAL-BELL.

SPECIFICATION forming part of Letters Patent N 0. 519,828, dated May 15, 1894. Application filed November 9, 1893. Serial No. 490,437. (No model.)

To all whom it may concern:

Be it known that I, WALTER S. ADAMS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have made certain new and useful Improvements in Alarm-Gongs, of which the following is a specification.

My invention has reference more particularly to gongs for use on cars, wherein a short quick sound, or a prolonged sound, may be effected at will, although it will be understood that my bell may be used for any desired purpose.

The object of my invention is to permit a clapper or hammer to act on the bell after the power has ceased to actuate it, as well as during the time of application of power.

Another object of the invention is to wholly disconnect the power applying mechanism fromtheclapper actuating device afterthefull stroke or action of the power applying mechanism has taken place to allow the clapper actuating device to have free and unretarded motion.

A further object of my invention is to simplify the construction of this class of gongs, so as to render the same elfective in use, cheap to manufacture and not liable to get out of order.

The invention consists in a gong having a swinging or hinged clapper or striker with a revoluble striker bar arranged to cause said clapper to act on the bell.

The invention further consists in a gong havinga swinging or hinged clapper or striker with a revoluble striker bar, a clutch for turning the latter and releasing it and means for actuating said clutch to turn the striker bar and for disconnecting said clutch therefrom to permit the latter to have free rotary motion.

The invention further consists in means to permit ready lubrication of the rotative parts Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure 1 is a side elevation of my improved bell showing it secured to car platform. Fig. 2 is a corresponding view looking from the opposite side thereof. Fig. 3 is a partly sectional edge view thereof looking from the right in Fig. 1, the parts being in the operating positions. Fig. 4 is a vertical sectional view thereof on the plane of the line m, 0c, Fig. 3. Fig. 5 is a vertical central cross section of the bell and its mechanism. Fig. 6 is a detail perspective view of the striker bar actuating rack, and, Fig. 7 is a detail perspective view of the striker bar and its clutch and pinion that is actuated by the rack.

In the accompanying drawings, in which similar numerals of reference indicate corresponding parts in the several views, 1 indicates a plate or supportwhich carries, or from which is suspended,- the main parts of the bell. In the example illustrated the plate or support 1 is shown carried by a board or the like 2 which may be the floor or platform of a car, or other part to which the bell may be attached.

3 is an arm or standard carried by or suspended from the plate 1, said arm carrying a shaft or rod at secured in place by the set screws 4, upon which shaft is carried a suit able bell or other resonant medium 5, shown secured thereto by a nut 6.

At 7 is a clapper or striker, shown hung within the hell 5 (or it may be otherwise carried) so as to strike against said bell. The clapper 7 is preferably supported by the shaft or rod 4:, and for this purpose said clapper is shown pivoted or hinged on an arm or projection 8 carried by the shaft or rod 4.. The arm or projection 8 may be secured on the 0 shaft or rod 4. by a screw 9, or otherwise as desired. It will be observed that the shaft 4 is horizontal and that the bell 5 extends vertically or at right angles to the shaft or rod 4, and parallel to the arm or standard 3 and 5 that the clapper 7 depends from the arm or support 8 (see Figs. 2 and 5).

At 10 is-a rotative striker barthat is adapted to actuate the clapper-7 to cause it to strike the bell or gong 5. The striker bar 10 is carzoo ried by, and adapted to rotate on, the shaft or rod 4, and it is preferably provided with av hub or boss 11 through which the shaft 4 passes, whereby said striker bar is permitted proper and even rotation on said shaft. The striker bar preferably projects on opposite sides of the shaft or rod 4 whereby it is balanced to permit proper rotation, and at its ends it is weighted or provided with enlargements 12 for giving strength and causing rotative momentum.

The striker bar carries projections 13, shown extending laterally therefrom in position to engage the clapper 7, which normally lies in the path of movement of said projections 13 (see Fig. 4), whereby as the striker bar 10 rotates the projections 13 will hit the clapper 7 and drive it against the bell 5.

At 14 is a rack for turning the striker bar 10, said rack being shown in the form of a segment, and it is arranged to mesh with a :pinion 15 mounted on the shaft 4 and arranged to rotate thereon.

The segmental rack 14 is shown hung on a pin or pivot 16 supported by the standard or arm 3, said pivot passing through an aperture 18 in said segmental rack.

The pinion 15 is connected with or forms part of a clutch 19 that is adapted to turn the striker bar 10. For simplicity of construction I have shown the pinion 15 as provided with clutch teeth 20 that are adapted to engage corresponding teeth 21 carried by or connected with the striker bar 10, the teeth 20 and 21 together forming the clutch 19. The teeth 20 and 21 may be suitably c011- nected with their respective parts 15 and 10, in Fig. 5 the teeth 20 being shown integral with pinion 15, the teeth 21 being shown carried by a plate 22 that is bolted, or otherwise suitably held, on striker bar 10. By this means the teeth 21 can be readily replaced if broken.

The pinion 15 is adapted to move along the shaft 4 to engage and disengage the teeth 20 and 21 to respectively cause rotation of, and

to permit free rotary movement of, the striker bar 10. For this purpose I have shown the pinion 15 somewhat wider than the rack 14, and provided with an annular flange 23 against which a projection 24 carried at one end of the rack 14 is adapted to bear to press the pinion and its teeth 20 out of engagement with the teeth 21 to release the latter and the striker bar 10, when the rack 14 has been turned the proper amount. The pinion 15 is carried by a sleeve 15, which also carries the teeth 20 and flange 23.

At 25 is a spring shown coiled on the shaft 4 and-pressing at one end against the standard 3 and at its other end against the pinion 15 (or sleeve 15) to keep the clutch teeth. 20 and 21 normally in engagement. But of course the spring 25 may be otherwise ar ranged for the same purpose if desired. The flange 23' (or the pinion 15 or sleeve 15) is shown provided with a recess 26 in which the spring 25 fits, whereby said spring is partially covered and the width of the parts is reduced.

The segmental rack 14 is shown provided with side projections or stops 27, 28 on its arms 14 that are adapted to engage projections or studs 29, 30 respectively carried by the plate 1 to limit the movement of said rack in opposite directions.

For the purpose of operating the rack 14 to rotate the striker bar 10 I have shown a foot presser rod 32 passing through an opening 33 in the plate 1, the presser rod having a head or enlargement 34 to receive the foot of the operator. To guide the presser rod 32 in the board or platform 2 I have shown the latter provided with a ferrule or guide 35 having an opening 36 that is aligned with the opening 33 in the plate 1. The presser rod 32 is adapted to bear or act on the rack 14, and for this purpose one of the bars 14 of said segmental rack is shown provided with a lag or projection 37 that is preferably rounded as clearlyshown in Fig. 6. The lug or projection 37 is shown extending substantially at right angles to the arm 14, and is at one side of the pivot 16 of the rack 14 and normally lies beneath the presser rod 32, as in Fig.1. The relative location of these parts is such that when the presser rod is depressed it will swing the rack l4onits pivot 16 and thereby turn the clutch 19 to rotate the striker bar 10.

For the purpose of holding the rack 14 in the normal position and to return it after it has been operated by the presser rod 32, 1 preferably use a spring 38 that at one end connects with the segmental rack 14, as by an apertured lug 39, and at its other end is connected with a projection or stud 40 carried by the plate 1 or support 2. By this arrangement the presser rod acts to drive the rack 14 to rotate the striker bar 10, and the spring 38 returns the rack 14 and presser rod 32 to their normal positions.

In order to conveniently lubricate the parts I make the standard 3 hollow, vertically at 41, and provide apertures 42 and 43 that are located contiguous to the shafts or pivots 4 and 16 (see Fig. 5). By this means when oil is fed into the opening or bore 41 it will lodge on the pivots 4 and 16 and pass along the same to the bearings of the pinion 15, striker bar 10 and rack 14. The plate or ferrule 35 carries a depending nipple44 that enters the bore 41, and is vertically aligned with the shafts or pivots 4 and 16 so that the lubricant will drop from said nipple upon said pivots.

The aperture in the nipple may be closed by a suitable plug, screw or cap. By the above arrangements the rotative parts of the bell in engagement, as in Fig. 5. To ring the bell pressure is applied to the presser rod 32 which acting on the segmental rack 14 turns the latter on its pivot, thereby rotating the pinion 15. The clutch teeth 20 and 21 now beiugin engagement cause the pinion to rotate or carry around the striker bar 10, which by means of the projections 13 (or otherwise) throws the clapper or hammer 7 against the bell 5 to ring or sound the latter. When the lug or projection 24 on the rack 14 reaches the flange 23 on the pinion 15 (or its sleeve 15*) said lug or projection will press the pinion along the shaft or rod 4 (toward the standard 3) and thus disengage the teeth and 21, as in Fig. 3. The striker bar 10 will now be free to rotate, the momentum acquired during the time it is moved by the rack 14 acting to carry it around. By this means a continuous ringing of the bell is effected,

even when the moving power has ceased to act directly on the striker bar. When the foot or moving power is removed from the presser rod 32 the spring 38 will act to restore the parts to their normal positions, the striker bar 10 meanwhile continuing to rotate as the teeth 20 and 21 can slip past each other, as the lug 24 will then have been carried away from the flange 23 on the pinion 15. It but a short sound is desired the presser rod 32 can be pushed down but little to give the striker bar a short rotation. Thus short or long sounds or ringing of the gong can be efiected at will. To keep the ferrule 35 from turning. I have provided it with an annular bushing 36, Fig. 4, having a rib or lug 45, (dotted lines Fig. 3) and have formed an annular bushing 46 on the plate 1 in which is formed the aperture 33 through which the presser rod 34 passes. On one side of the annular bushing 46 I have formedaslot 47 into which the rib 45 enters, thus preventing the ferrule 35 from turning.

It is evident that the details of construction and location and arrangement of parts can be changed or modified without departing from the spirit of my invention.
